This medication is an antihistamine and decongestant combination which provides relief of seasonal allergy symptoms such as watery or itchy eyes, runny nose, sneezing, itchy throat, and stuffy nose (nasal congestion).

How To Use Wal-Fex D 12 Hour Oral

Take this medication by mouth on an empty stomach 1 hour before or 2 hours after a meal as directed by your doctor. High-fat meals may decrease the absorption of the medicine into your bloodstream, decreasing its effectiveness.

Do not crush or chew extended-release tablets. Doing so can release all of the drug at once, increasing the risk of side effects. Also, do not split the tablets unless they have a score line and your doctor or pharmacist tells you to do so. Swallow the whole or split tablet without crushing or chewing.

Taking this drug with apple, grapefruit, or orange juice may decrease the absorption of fexofenadine. Avoid taking this drug with these types of fruit juices. If possible, take it with water instead.

Antacids containing aluminum and magnesium can decrease the absorption of this drug. Do not take antacids within 2 hours of taking this medication.

Do not increase your dose or take this more often than directed.

Do not take this medication for several days before allergy testing since test results can be affected. Consult your doctor or pharmacist for more information.
